Sediment samples were collected from the coastal area of the Petrochemical Special Economic Zone of Musa Bay. The samples were analyzed to determine the degree of hydrocarbon contamination and identify the sources of PAHs which were evaluated by employing the ratios of specific PAHs compounds and principal component analysis (PCA). The levels of TPH concentration in the studied area were relatively moderate compared to the world-wide chronically oil-contaminated locations. The concentration of total PAHs was lower than those in other parts of the Musa Bay but approached the NOAA sediment quality guideline value.

Surface sediments at West Port on the west coast of Peninsular Malaysia were monitored to evaluate the spatial distribution of heavy metals: As, Cu, Cd, Cr, Hg, Pb and Zn. Sediment samples were collected from 10 stations, at three month intervals from November 2009 to October 2010. The degree of sediment contamination and ecological risk factor were estimated to assess contamination status and adverse biological effects. The ecological risk assessment indicates that living organisms are at high risk of Cd and Hg exposure and this is considered a critical environmental issue. Spatial distribution maps of heavy metals would facilitate identification of pollution sources and vulnerable sites.
